Cellulose Fiber Chips, are the natural and safer alternative to Orris Root fixative. Orris Root can cause allergic reaction and possible skin irritations. Cellulose Fiber Chips can be used in making herbal potpourri or a filling for sachets. The fiber is a good absorbent media for fragrance oils, allowing maximum saturation and oil content because many traditional potpourri botanicals cannot absorb much oil or permit penetration.
